Chlorella sorokiniana UTEX 2805, a heat-tolerant microalga, was cultured autotrophically in outdoor tubular photobioreactor in spring and summer. Particularly, an industrial flue gas generated by combustion of liquefied natural gas (LNG) and a natural sunlight were used for the economic production of biodiesel from the microalgal biomass. After performing a primary assessment of the biomass production under two temperature conditions (23℃, 36℃) in laboratory-scale, the cells were cultured in outdoor conditions under photoautotrophic condition in spring and summer. As a result, C. sorokiniana showed high tolerance to flue gas and high temperature. In summer, the cell exhibited the remarkable lipid content (＞35% of dry biomass) under N-starvation conditions to accelerate an intercellular oil accumulation. C. sorokiniana will improve microalgal biodiesel production under high temperature in outdoor conditions. |
